lhis invention relates to anew and useful device in the nature of an entilfreezing water heater, the device being particulerly'adepted for use in connection with water cooled internal combustion engines for the purpose of heating. the cooling water to prevent freezing in cold weather.

The object of the invention is to provide an antilreezing water hester of novel construction and arren einent of ports, herein after more fully described, claimed, and illustrrited in the accompanying drawing, in which:

Fig. 6 is a sectional View taken on the line 6-6 of Figure 2. Fig. 7 is an enlarged sectional View of the temperature regulating pin.

Fig. 8 is a schematic Wiring diagram of the device.

The internal combustion engine 10, is rovided with a fan 11, driven by a suitable elt 11, a water pump 12, attached to the water jacket 13, and connected to the cooling radiator 14 by means ofa hose 15. The water outlet manifold 16 is also connected to the cooling radiator 14 by means of a second hose 17. The above mentioned parts are common construction and such as ordinarily used in mot-or vehicles, aeroplanes, and the like. h

It will be understo. that my improved device, designated by the numeral 18 1S suitably connected to the hose 15, or to the hose 17, as clearly shown in Figure 1 of the eccompanying drawin I As here embodied my improved dev comprises a. bod 19, of hollow cylindrical construction, an having two outlets 20 end 21, oppositely located. The body 19 is also provided with aperture to receive the supporting member 22, which is removehly is an enlarged fragmentary sec- 55 of Figend is coated with attached to the upper extremity of the body 19, by threeds, or any similar mew. The supporting; rneinher is of hollow construcnon, end hose, lower protruding portion 23, located between heretobefore mentioned two outlets 20 and of the body 19.

The plug 24-, is reroovahly attached. to the lower protruding portion 23 of the supporting member 22, by threads, or any similar means. The pin; 24% has on axial cylindrical recess 'lhe hosting element hes at lower portion e. slidsble fit on the periphery of the upper portion of the plug 24, asbestos, 27, or eny simi lar non-h-eat conducting materiel, the shell 28 is provided to protect the asbestos 2?, the shell 28 is e slidelcle lit in the lower portion of the body 19. The flange 29 of the heating; element is also insulated from the body 19 by asbestos 30, or any similar non-hoot conducting materiel.

The lower insulating block 31, preterebly of hard rubber, is of hollow cylindrical construction, o slideble fit in the supporting member 92;. The upper insulating block 32, of similar material is also oi hollow cylindrical construction, at slidable lit in the sup porting member 22, and has an upper protruding portion 33.

The heating element, by its flange 29, the lower insulating block 31, end the upper in sulating block 32, are attached to @ttCl l other by moons of screws 34.

The disc 35, circular shaped is located in the lower insulating block: 31, end hos prongs 36 protruding downwardly in the lower insulating block 31.

The pin 38 is e slidable fit in the upper insulating block 32 end hes preferably, poi tions 38, of somewhat larger diameter in the pin proper. The in 38 hes suitably st tached thereto, by e enge 59, o. second disc 54:, having; it protruding control portion at. it being understood that the send protrud ing central portion is normally in contact with the disc 35, and that the said second disc encloses or seals the exiel aperture 55 and the semicircular recess 56 in the pin 38, and the said axial aperture and the said semicircular recess ere filled with mercury, or any similar substance before the second disc 54 is attached to the pin 38.

The circuit breaker 40 is sdiustebly ettached to the upper extremity of the pin 38 by income of nuts ll, screwed thereon. The circuit breaker if; hes down till wardly protruding portions 4, a slidable fit in apertures suitably located in the protruding portion 33 of the upper insulating block 32.

The coil spring 43 is superimposed between the upper insulating block 32 and the disc 39, and is located in a circular slot 44:, so as to normally hold the disc 39 in a don l1 ward position, in contact with the diaphragm 35.

The contact points 49 and 50 are connected to the screws 34 by the extended portions 51.

The cap i5 or cover is removably attached to the supporting member 22 b threads, or any similar suitable means, an is provided with a plurality of apertures 57 conveniently located in its sides above the supporting member 22, and has also a centrally ocated aperture at its top, to accommodate a bushing 48, preferably of hard rubber, suitably attachedv thereto through which the insulated electric wires 58, 59, 60 and 61 are passed.

The wire 58 is connected to the one of the screws 34 and to the electric light 53, the wire 59 is connected to the same screw 34: and to a socket 62, of ordinary construction, such as would be used to connect my improved device to an electric circuit, the wire 59 has connected thereto a wire 63 which is also connected to a storage battery 52. The wire 61 is connected to the socket 62, and a wire 66 is connected to the wire 61 and to the storage battery 52. Switches, of

ordinary construction, 64 and 65, are provided in the two circuits.

It will be further understood that functioning or operation of my improved device is as follows: By means of the electric current through the lower portion 26 of the heating element, the water used to cool the engine will be heated, when the water has been heated to the desired temperature, the heat from the heating element will expand the second disc 54 which will raise the pin 38, the circuit breaker 40 will be raised also and the electric current will no longer flow through the heating element.

It will be further understood that the superimposed coil spring 43 will cause the circuit breaker 40 to return or drop to a normal position when the second disc 35 becomes cool and returns to its normal posi tion, which will again allow the electric current to flow through the heating element, and the operationwill again be repeated, when the cooling water of the engine has been heated to the desired temperature.

It will also be understood that the electric light bulb will be lighted only when the electric current is flowing through the heating element.

It will also be understood that the nuts 41 screwed onto the upper extremity of the pin 38, may be adjusted to regulate the functioning of my improved device, by raising or lowering the clrcuit breaker 40.

While I have above described the preferred form, construction and arrangement of the several elements employed, it will be understood that the-device is nevertheless, susceptible of considerable modification therein, and I therefore reserve the privile e of resorting to all such changes'as may fairly embodied within the spirit and scope of the invention as claimed.
